摘要：

The first measurements of the invariant differential cross sections of inclusive pi(0) and eta meson production with ALICE are presented for pp collisions at root s = 0.9 and 7 TeV, Next-to-Leading Order perturbative QCD calculations overestimate the data at root s = 7 TeV, but are consistent with the pi(0) spectrum at root s = 0.9 TeV and with the measured pi(0)/eta cross section ratio at root s = 7 TeV. The nuclear modification factors (R-AA) of pi(0) production at different centralities show a strong suppression with respect to pp collisions.
